Hi Rob!
when you say:

ByteString.
How are you accomplishing that? I see from your example that the elements
of your array aren't proto messages, so maybe .Net has its own
serialization format that non-.Net languages aren't aware of? In that case,
the only real solution I can think of would be to formalize that
serialization by using protos. For example:
message RangeData {
int32 num_rows = 1;
int32 num_columns = 2;
repeated Row row = 3;
}
message Row {
repeated Value value = 1;
}
message Value {
oneof value {
string text = 1;
double number = 2;
}
}
or, alternatively, if you're not going to mix the strings and the numbers:
message RangeData {
repeated string row_name = 1;
repeated string column_name = 2;
repeated Row row = 3;
}
message Row {
repeated double value = 1;
}
Hope that helps,
Jorge
